Publish overview

Publish takes a snapshot of your project and hosts it on a public URL so anyone can open it — separate from the live preview you use while building.

Preview vs published

	Live preview	Published app
Audience	You (and collaborators) while building	Anyone with the link (or, on Business, only your workspace’s members)
Lifecycle	Pauses when idle	Hosted publicly; uses monthly Cloud credits
Purpose	Iterate quickly	Share / ship

What you need

A project that runs in Preview
Verified email on your account
Available slug (Mythex subdomain)
Cloud credits available (Free pauses the LIVE app when they run out)

Usage is gated by monthly Cloud credits, separate from the Build credits used for chat. Free can have up to 3 published apps at once; paid plans have no cap. Free apps show a small “Built with Mythex” badge; paid plans don’t.

What address does my app get?

	Address
An app you publish for the first time	`{slug}.mythex.app`
An app that was already published on `{slug}.mythex.ai`	Keeps `{slug}.mythex.ai`, also when you publish it again, so links you shared, sign-in settings with outside providers and visitors’ sessions keep working
The other address	Every published app also answers on the other one: `{slug}.mythex.ai` and `{slug}.mythex.app` show the same app
Your own domain (Pro and up)	`app.example.com` — its CNAME points at `{slug}.mythex.ai` either way. See Custom domains
Preview share links (while building)	Stay on `mythex.ai`; previews never use `mythex.app`

The Publish dialog shows the address your app will really get before you publish. In a team workspace, publishing needs the Editor role or higher, and an Enterprise workspace can limit it to admins or require approval. See Who can publish and open apps.
